Cable trench cover plate and preparation method thereof
The invention provides a cable trench cover plate and a preparation method, and belongs to the field of electric power engineering materials. The cover plate comprises reinforcing ribs parallel to the longitudinal edges of the plate, steel pipes crossed with the reinforcing ribs, lower-layer prepared concrete for pouring and covering the reinforcing ribs and a half layer of the steel pipes, and upper-layer prepared concrete covering the lower-layer prepared concrete; the other half layer of the steel pipe extends into the upper-layer prepared concrete, a phase change energy storage material is poured into the steel pipe, and the two ends of the steel pipe are blocked by elastic materials; the upper-layer prepared concrete is an insulating layer, and graphene oxide is added into the lower-layer prepared concrete. A more uniform temperature change environment is obtained in the cover plate and the cable trench, the temperature stress in the cover plate is reduced, and the service life of the cable is prolonged; the cover plate lower layer has good conductivity and effectively eliminates static electricity in the cable trench, and meanwhile the insulating upper layer ensures the insulating property of the cover plate to the outside. The cover plate is improved in toughness and compressive strength and can be applied to various scenes.
本发明提供了一种电缆沟盖板及制备方法，属于电力工程材料领域。所述盖板包括：与板纵向边平行的加强筋、与加强筋交叉设置的钢管、浇筑并覆盖加强筋及半层钢管的下层配制混凝土及覆盖于下层配制混凝土上的上层配制混凝土；所述钢管的另半层延伸至上层配制混凝土内，且钢管内灌注相变储能材料，钢管两端由弹性材料封堵；所述上层配制混凝土为绝缘层，下层配制混凝土添加氧化石墨烯。本发明使得盖板及电缆沟内部获得更加均匀的温变环境，减少盖板内部温度应力，同时提高电缆的使用寿命；盖板下层具有较好的导电性，有效消除电缆沟内部的静电，同时绝缘上层保证盖板对外界的绝缘性；提高了盖板韧性、抗压强度，能够应用于各种场景。
